SYRINGE.

`To all whom i1/may concem:

Be it known that I, THoMs R. Mc-

NERTHNEY, a citizen of the United States,

and a resident of Tacoma, in the county of Pierce and State of Washington, have invented a new and Improved. Syringe, of which the following is afull, clear, and exact description.`

The purpose of this invention is to provide novel details of construction for a combined douche and syringe, which by the action of gravity and subsequent production of a partial vacuum, effect a thorough but gentle embrocation of `diseased walls of the ,os, uterus and vagina, with a medicinal liquid, and then remove the medicament, together with pus or other unhealthy secretions, by a free liquid irrigation of the diseased tissue, this result being e'ected by the establishment "of `a partial vacuum in parts of the device.

rlhe #invention further comprehends the application ofa suitable medicament and a subsequent irrigation and ejection of the medicament to,` and from the ear, nose or other diseased cavity in the body, by means of the improved syringe.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claims. l

Reference is to be had to the accompanying drawings forming a part of this specification, j in which similar characters of reference indicate corresponding parts in all theviews.

Figure l is a perspective view showing the deviceV arranged for service in connection with a source `of water supply under pressure; Fig. 2 is an enlarged longitudinal sectional view of novel parts; and Fig. 3 is a longitudinal sectional view of another novel detail of construction.

.l In the drawings which illustrate the constructionv and arrangement of novel details for service,`5 indicates a liquid receptacle of ordinary form, such as is employed for holding liquid to be discharged as a spray or douche. As usual, the douche receptacle 5 is adapted for pendent support on a side wall of a room, such as a bath room, indicated at Ain Fig. 1, and fromthe lower wall of the receptacle `5, a preferably iiexible tube 6 is downwardly extended. In the tube 6, a valve a; isintroduced, which controls the fiow of liquid from the receptacle 5. Pref- Specification of Letters Patent.

erably the lower end of the pendent tube 6, is located adjacent to the faucet b that controls the iiow of water into a wash basin 7 that is provided with a discharge pipe 7a,

which extends from the bottom of the basin 7 in the ordinary way.

A flush pipe 8, that may be of metal, is furnished with an elastic coupling joint c that is fitted water tight but removably upon the nozzle end b of the faucet b, and depends therefrom to a point near the bottom of the basin 7. On the flush pipe 8, below the upper end a suitable distance, a short tubular branch d is formed, affording an inlet passage for the insertion of a suction pipe 9 thereinto, and as shown clearly in Fig. 2, said pipe is bent into right angular form, one member 9a thereof extending down within the flush pipe and the other member projectingV laterally therefrom. Upon the outer end of the suction pipe 9, one end of a preferably rubber hose section l0 is removably mounted, the joint e between said ends being air and water tight.

An important detail of the improvement consists of a syringe barrel which is formed preferably of metal or hard rubber. This barrel ll is mainly straight, but at one end is forked, thus producing two integral branches ll, 11b thereon, which are about equal in length and at their free ends have slight enlargements g thereon. In the barrel 11, that is a true cylinder, a partition wall It is longitudinally and centrally secured extending from the angle or crotch t' where the branches 112,11", are joined to the end of the barrel 11, to a point near the other end of said barrel, as shown in Fig. 3. The free end of the barrel 11 is mainly closed with a convex wall, that is centrally perforated, as shown at m in Fig. 3, and directly opposite each side of the partition wall 7i, an orifice is formed in the cylindrical wall of the barrel, one orifice n being nearer the end of the :barrel than the other orifice n', but this is not material. Upon the enlargement g on the end of the branch 11a, the remaining end of the hose section l0 is mounted removably, the joint therebetween being air and water tight, and iii said hose section a valve 0 may be introduced which affords control of the liquid flowing through said hose section. VUpon the lower end of the tube 6, one end of a hose section 6a is mounted, air and water tight, by a detachable connection p, and from said detachable connection the hose section 6a is extended for sucha length as will permit the other end thereof to be mounted air and water tight but detachably, upon the enlargement g of the branch pipe 11b.

In operation, it will be seen that liquid for application to a diseased membrane, such as' the mucous lining of a female organ, is placed in sufficient quantity in the receptacle 5. Then, upon a proper insertion of the nozzle end of the barrel 11 Within the diseased organ, the valve a is opened so as to permit the gentle flow of the liquid, that may be of an antiseptic nature, down through the hose section 6a into and through the branch pipe 11b of the barrel 11, from which the disinfecting liquidis conveyed by pressure of gravity through the conduit fr in the syringe barrel 1l, that is a virtual extension of said branch pipe. Alternately with the opening of the valve a, the valve o and faucet b are opened, which will cause a forcible discharge from the faucet down the flush pipe 8. The flow of water through the pipe 8 will produce a partial vacuum in the hose section 10, branch l1a and passage 7" in the barrel 11.

The exhaustion of air from the conduit or passage r in the barrel l1 causes the liquid embrocation that pervades the vagina and uterus, to pass upward through said conduit r and thence directly through the flush pipe and basin pipe 7'a to a point of discharge. The intake or flow through the valve a is alternated by the outtake or flow through the valve o. When the valve a is opened the antiseptic fluid passes out through the openings in the barrel 1l and remains in contact with the diseased or inflamed tissues for a second or two; then the outtake valve o is opened and by suction the antiseptic liquid with the pus, etc. is carried away. The in-Y take valve a 1s again opened and the above operation is repeated during the entire progress of the treatment.

It will be evident that the passage of the antiseptic and detergent liquid into and out of the female organ, as hereinbefore explained, will remove pus and all unhealthy secretions from the diseased membrane, and thoroughly cleanse the same. Furthermore, if found desirable, a healing embrocation of the diseased parts, may be effected by charging the receptacle 5 with a suitable medicinal iuid compound and passing the same through the described apparatus, so as to further embrocate the inflamed and diseased membrane.

It is to be understood that any other source of water supply under pressure may be utilized and effect the same results; as for example, the supply faucet for a bath tub, or for a sink basin, may be substituted for a faucet that is a fixture for a fixed Wash bowl.

The operation of the improved device is under complete control, avoids injurious pressure on diseased parts, and is cleanly in operation, as there need be no escape of liquid therefrom, thus eliminating all danger of contaminating the nurse or medical attendant who administers the treatment to a patient.

The improvement may by a proper proportion in diameter of the barrel l1, be used as a catheter for application to the male organ, either to embrocate diseased lining tissue or for the irrigation of the prostate gland and inner wall of the bladder, for relief of stricture or like ailments.

One of the most important uses of the device as a catheter is in treating chronic posterior gonorrheal urethritis, z'. e. chronic gonorrhea that Y'has extended far back into the urethra. Here the disease has diminished `the amount of blood supply. By the use of a small amount of irrigation, (cutting off intake,) with a marked degree of evacuation, (opening wide to outtake) there is an increased blood supply to the part (called suction hyperemia of Bier).

The device may also be used to allay fever in the uterus or rectum, by its insertion within the latter and the introduction of a cooling liquid thereinto. It is also adapted for the embrocation of the interior walls or sinuses of the ear or nose, in the treatment of diseases of these organs, as it enables the application of an antiseptic or healingV liquid directly to the diseased tissue, and a removal of pus or other unhealthy secretions from such cavities in the body.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
